Osmoregulation

Question 1

hyperosmotic solution

Answer 1

solute concentration is higher outside the cell than inside the cell

Question 2

hyposmotic solution

Answer 2

solute concentration is higher inside the cell than outside

Question 3

ionic and osmotic challenges: marine environments

Answer 3

animals tend to gain salts and lose water

Question 4

ionic and osmotic challenges (freshwater environment)

Answer 4

animals tend to gain water and lose salts

Question 5

ionic and osmotic challenges- terrestrial environments

Answer 5

animals tend to lose water

Question 6

Osmoconformers

Answer 6

change their bodies osmolarity to be similar to their environment. many invertebrates are osmoconformers,

Question 7

osmoregulators

Answer 7

osmolarity is constant regardless of the environment, most vertebrates

Question 8

ionoconforms

Answer 8

exert little control over ion profile with the extracellular space, many invertebrates

Question 9

ionoregulators

Answer 9

control ion profile within their extracellular space, most vertebrates

Question 10

blood concentration osmoregulators vs conformors

Answer 10

ionoregulators blood concentration is much lower than inoconformers
